| 0                    | Digit, required. This element will accept any single digit between 0 and 9.                                                                                                                                                                                                                                                                                                                                          |

### Accessing the StandardMaskTextBoxProvider

When the mask type is set to *Standard* you can access the **StandardMaskTextBoxProvider** by casting to that appropriate type.

```C#
this.radMaskedEditBox1.MaskType = MaskType.Standard;
StandardMaskTextBoxProvider standardProvider = this.radMaskedEditBox1.MaskedEditBoxElement.Provider as StandardMaskTextBoxProvider;
```

```VB.NET
Me.RadMaskedEditBox1.MaskType = MaskType.Standard
Dim standardProvider As StandardMaskTextBoxProvider = TryCast(Me.RadMaskedEditBox1.MaskedEditBoxElement.Provider, StandardMaskTextBoxProvider)
```

### Useful properties

**StandardMaskTextBoxProvider** exposes the following useful properties:

* **Mask**: Gets the mask.
* **Value**: Gets or sets the value.
* **MaskCompleted**: Gets a value indicating whether all required inputs have been entered into the formatted string.
* **MaskFull**: Gets a value indicating whether all required and optional inputs have been entered into the formatted string.
* **PromptChar**: Gets or sets the character used to prompt the user for input.
* **ResetOnPrompt**: Gets or sets a value that determines how an input character that matches the prompt character should be handled. When *true*, the prompt character entered as input causes the current editable position in the mask to be reset. Otherwise, if *false*, the entered prompt character will be processed as a normal input character. The default is *true*.
* **ResetOnSpace**: Gets or sets a value that determines how a space input character should be handled. When *true*, entering the space input character causes the current editable position in the mask to be reset. Otherwise, if *false*, the entered space character will be processed as a normal input character. The default is *true*.

> note By default, when the user is typing before already typed text, the text is overridden. If the *Insert* key is pressed you can insert characters instead of replacing them.
